Emergence, by Killa

It had always been his Achilles’ heel; he couldn’t seem to help being fascinated by possibilities. And that was the crux of it, wasn’t it? Because he and MacLeod between them were nothing if not possibility… Infinite possibility, just waiting to happen.

Adult, first time. A lot of Duncan/Methos fic wallows too much in angst and emotions, especially where Methos and his past are concerned, imho. This, on the other hand, feels like something that could (should) happen, right down to the not-so-clear cut ending.
